Real comparison, plain math.
SE-tax savings
S-Corp lets you split profit into "reasonable salary" (subject to 15.3% SE tax) + distributions (not). Saves 15.3% × distribution portion.
Breakeven at ~$60K
Below ~$60K profit, S-Corp compliance costs exceed savings. Above $60K, savings climb. Above $150K, savings substantial.
Reasonable salary required
IRS audits target low S-Corp salaries. Industry benchmarks + market rate. Too-low salary triggers reclassification + back taxes.
Added compliance
S-Corp adds: payroll system, W-2, quarterly 941, annual 940, K-1 generation, Form 1120-S. ~$1.5K-$3K/year compliance.

Common questions.
What is the difference between an LLC and an S-corp?
How does an S-corp election save taxes?
An S-corp lets owners split income between salary and distributions, and distributions are not subject to self-employment tax, so an active owner earning enough profit can reduce self-employment tax versus a default LLC. We flag whether your profit level makes the election worthwhile so you do not add payroll complexity for little benefit.
When should an LLC elect S-corp status?
Generally once the business earns enough profit that the self-employment tax savings on distributions outweigh the added payroll and administrative cost, which is a specific threshold for each owner. We flag whether your numbers justify the election so it saves money rather than just adding complexity.
What is the reasonable salary requirement?
An S-corp owner who works in the business must pay themselves a reasonable salary subject to payroll taxes before taking distributions, and setting it too low invites IRS scrutiny. We flag how the reasonable-salary rule works so your S-corp captures the benefit without creating an audit risk.
Does electing S-corp change my legal entity?
No: your LLC stays an LLC legally and simply changes how it is taxed, so you keep the LLC's liability protection and flexibility while gaining S-corp tax treatment. We flag this so you understand the election is a tax choice layered on your existing entity, not a new entity.
What are the downsides of an S-corp?
It adds payroll, a separate S-corp tax return, and stricter rules, and it limits who can own the business, so the tax savings must outweigh the added cost and complexity. We flag the trade-offs so you elect S-corp status only when your situation genuinely benefits rather than by default.
Can any LLC elect S-corp status?
Most can, but the S-corp has ownership restrictions, a cap on shareholders, US-person owners, and one class of stock, so not every business qualifies. We flag whether your ownership fits the S-corp requirements so the election is actually available to you before you plan around it.
How do I make the election?
You file the S-corp election with the IRS within the timing rules, and late-election relief is sometimes available, so timing matters. We handle the election and flag the reasonable-salary and payroll setup that comes with it, so your LLC's S-corp treatment is filed correctly and on time.
Can File.Business set up an LLC with an S-corp election?
Yes: we form the LLC, obtain the EIN, and file the S-corp election when it benefits you, while flagging the reasonable-salary and payroll requirements, so your business gets the tax treatment that fits its profit level, coordinated with your tax advisor.
